1 193 932 Specification of Letters Patent. Patented Aug; 8, 1916Application filed larch 8, 1916. Serial No. 82,872.

Toall'wkom it may concern: desired, an automatic door may be providedBeitkuownthatLWnmnOsesx Snsnnom, a citizen of the United States, and a.resident of the borough of Brookl n,

5 in the city and State of New York, have mvented certain new and usefulIm rovements in Trucks, of which the follow ng 13 a speeificatim Myinvmtion relates to dqmpmg trncks, to and has for one of its principalob3ects to provide a truck in which the body portion is adapted tobeelevated to dmnp the eontenisatthereanthemechamsmrmsmgsaid body beingoperatsl from the front of the waysinoperatweposifion whichever way thefront axle of the truck,oratraetor,ineasethesame1sem- P d-is m i- Theinvention in the novel mm- -monnted inthefi-amell,thenforwardly at theback of the body, which, when the body is raised into the dumpingposition, W111 open and allow the contents to slide out. devicecomprises a door proper 15, suspended fi'om hooks 16. Pivoted at 17 onthe under side of the movable body 12 is an L-shaped latch member 18,one end of which is adapted to engage with a letorally extending pin 19on the door 15, and the other end of which is connected bymeansofalinkflowiththeframell.

.Secnred to the under side of the body 12 are downwardly projectingmembers 21, to which are pivoted the upper ends of rods 22. The lowerends of these rods are eonneeted together by a ems-bar 23, to whichissecnredoneendofaehainfi. Thechain 24 pass upward and over a, pulley 25mounted in the fi-hme 11, thm downwardly and forwardly and under apulley 26, also horizontally end betweentwo horizonpnlleys on thetractor, and

The operation of my invention is as followszThepartsofthewagonarenomnllyintheposifiondiownbythefnlllinesin Fig. L When in this position, thewagon may be loaded, and hauled irom place toplaoebymeansofthehnotororotherwise. Whenitisdesiredtodmnptheloadtheshaft 32 is roiafing the drum 29 hymeansofthewormfiandgearrmthe chain 2%is wound up, raising the crossbar23andvertiea1rods22,flmsliftingthecarryingbodyfiintotheposition diown bythe dottedlinesinFig. 1. Asthebodyis raised, the link 20 pushes against the latch 18, raisingit out ofwith the pin 19, and allowing the door 15 to swingopen by its weightSimilarly, when 105 the wagon is lowered, the door into its closedposit-ion and be engaged by the latch 18.

It often happens that it is desired to dump the contents of the truckwhen the 5 frontwheels or the tcactor are not in their usual position.Whenever the tractor is swung to one side, as is shown in Fig. 3 thepulleys 27 will be swung more or less into the pos'tions shown in thedotted lines in Fig. 3, the chain bearing laterally against one or theother of these pulleys according to the directionin which the tractor isturned- It will thus be obvious that in whatever position the frontaxleor tractor may be, the chain will always be led in an approximatelyforward direction from the pulley 26 (so the pulleys 27, and thence tothe drum 29 in a direction approximately at right angles to the axis ofthis drum 'and that the contents of the carrying body may be dumpedregal-tiles of the angle which the tractor and truck may form with eachother. The pulleys 2? are situated at such a point; forwan'lly of the.pivotal point of the that the distance between the pulley 26 and" drum29, as followed by thechainfld, will not be y changed when the is to oneside or i ee k o 30 fieadvanssgesof my invention will be itsico and modeof op- .g n m thick, with third fgdepted torpnll operafively con nectedwith said body and adapted to pass around said first named pulley andbetween said second named pulleys, and means adapted to pull said chain.
